In the fast-evolving world of biomedical research, the ability to accurately classify and analyze cells is pivotal. Cell isolation and sorting technologies provide essential tools for researchers in several prominent fields, including immunology, cancer research, and stem cell studies.  Among the most prominent techniques are fluorescence-activated cell sorting (FACS), magnetic-activated cell sorting (MACS), and the emerging buoyancy-activated cell sorting (BACS™). Each of these methods has unique advantages and challenges, shaping …

Cytotoxic T Cells A cytotoxic T cell (CD8+ T cell) is a type of T cell responsible for eliminating substances the immune system identifies as harmful. Cytotoxic T cells play a critical role in limiting infections and bacteria in the body. Functions of Cytotoxic T Cells Viruses and other bacteria attack by multiplying and spreading diseases as infected cells. Once a cell is infected, there is no way for antibodies …

How Is Plasma Separated From Blood? Each blood cell type has its own unique purpose and function and separating the various blood components allows scientists to analyze specific cell types. For example, human leukocytes can be used to study immunological functions such as cytokine production and surface marker expression. Other blood components can be used to detect diseases. Once separated, blood cells can be further isolated into cell subsets. Components …

We hear this question all the time: How many cells can a microbubble lift? For many users, the most important questions around microbubble-based cell separation kits have to do with how many microbubbles to add to a sample. Answering this question requires getting into the total lifting capacity of a microbubble. Part of the answer derives from how a microbubble engages cells, clumps of cells, or even larger structures such …
